Ethics approval(s)Approved 11/03/2019, Kyungpook National University Bioethics Review Committee (Department of preventive Dentistry School of Dentistry, Kyungpook National University 2177 Dalgubeol-daero, Jung-gu, Daegu 41940, Korea; +82 (0)53 2000 5430; knuiars@knu.ac.kr), ref: KNU 2019-0009

InterventionThis is a double-blinded randomized clinical trial that referred to the Consolidated Standards of Reporting Trials (CONSORT) 2010 guideline from design to completion.

Healthy adult applicants interested in tooth whitening are recruited through snowball sampling. The effectiveness of whitening is confirmed by attaching a patch containing 3.0% peroxide and a primer containing a mitigating component for 30 minutes for 10 days. In addition, safety is checked by examining the presence or absence of side effects caused by whitening through self-filling questionnaires and oral examinations.

When applied for at least 30 minutes with a self-whitening patch containing 3.0% peroxide, the efficacy of whitening compared to the placebo-controlled group is confirmed, and the difference between application times of 30 minutes is confirmed.

After applying the taurine-containing primer, a self-administered questionnaire completed asking about the patient's subjective symptoms and an oral examination is carried out for the side effects of whitening to confirm the clinical safety.

Total duration of intervention and follow-up: 18/03/2019 to 26/04/2019.
